유성(遊星) 김준곤 유성의 설교: 역사적 분석과 그 화두(話頭)

김정우(Jungwoo Kim) 신학지남사 2019 신학지남 Vol.86 No.3

The aim of this paper is to analzye the world of Late Rev. Joon Gon Kim’s Sermons published in CCC Letters (1964∼2005) from rhetorical perspective. The author finds three major characteristics of his sermon in terms of their originality in the history of sermons, the use of clear images and poetical reformulation of biblical narratives. The main genre of his sermon can be identified with a storytelling narrative preaching with preeminent characterization of biblical heroes and heroines. As a preacher who illuminated the word of God in his historical context with a widespread sensitivity of his times like Albert Camus and leap of faith like Soeren Kierkegaard, the author divides his preaching into three main periods such as (1) Incipient Period (1958∼1974): Missional preaching to college students and National Evangelism, (2) CCC Chapel Period (1976∼1989): Pastoral preaching to college students and the Whole counsel of God, (3) the Latter Period (1990∼2005): Engagement of Christian Charity to the North Korea and “One Single Answer to Hundred Questions” in Jesus. One major question of his sermon throughout his whole life has been “where does the river of spirit history (namely, religions, philosophies, literatures and cultures) flow?” The author summarizes the major distinguishing legacy of his sermon in terms of “Gospel preaching” in the stage of modern history of Korea, “Gospel meditation” narrated in the stage of intellectual history of humanity and “Visionary sermon” aiming at eschatological mission community in the context of historical upheavals.

This paper is the study of the therapeutic effects of poetry on the older generation. This study focused on the two cases; the one was the aged who had recently completed a literacy program in lifelong education, and the other was a professional poet who had suffered from a serious illness. The aged got stated wrote poems, they was unskilled but incorporated personal experience into their works. The poems have notable some features; taking out painful memories, shifting to positive psychological states, and enjoying their writing by making use of literary devices. Famous poet Kim Gwang Seop had suffered a cerebral hemorrhage in 1965, but he continued to write poems till he died. In his later poems, Kim’s mind has changed from despair to acceptance, and his creating poems helped promote a state of recovery with the body. Although there is a great difference between the aged amateur poets`` works and the professional poet``s poems, but their poems have some features in common, which were acceptance or taking out, consolation and happiness, relaxed state and philosophical view of life. The features could be the typical aspects in enjoying literature by the old age and healing by poetry therapy.

김정우,김진성,이희수,강도원,김정욱,Kim, Jung-Woo,Kim, Jin-Seong,Lee, Hee-Soo,Kang, Do-Won,Kim, Jeong-Wook 한국결정성장학회 2009 韓國結晶成長學會誌 Vol.19 No.2

$BaTiO_3$ 입자 크기가 MLCCs의 절연 특성 및 MLCCs 특성 열화에 미치는 영향을 알아보기 위해 서로 다른 입자를 사용하여 제작한 MLCCs의 가속열화시험을 $150^{\circ}C$, 75 V조건에서 실시하였다. 실험에 사용된 MLCCs는 각각 $0.525{\mu}m$, $0.555{\mu}m$, $0.580{\mu}m$의 입자 크기를 가지는 $BaTiO_3$와 Ni계 전극을 사용하여 상용화된 공정을 통해 제조되었다. 제조된 MLCCs에 대해 정상 유무 확인을 위해 X5R조건 하에서 TCC(Temperature Coefficient of Capacitance) 측정을 통해 유전 변화율에 대해 알아보았다. 세 가지 입자 크기에 따른 절연저항의 거동을 알아보기 위해 BDV(Breakdown Voltage)를 실시하였고, 가속열화시험 후 입자의 크기에 따른 MLCCs 열화의 정도와 원인을 알아보기 위해 XPS(If-ray photoelectron spectroscopy)를 통해 고장분석을 하였다. $BaTiO_3$의 입자 크기가 작을수록 절연파괴저항 및 절연저항 열화에 우수한 특성을 나타내었고, XPS 분석 결과 확인된 NiO peak과 $BaTiO_3$ peak 감소를 통해 MLCCs 열화원인이 유전체의 산소 환원과 환원된 산소와 전극간 반응임을 알 수 있었다. The accelerated life time test of the MLCCs with different $BaTiO_3$ particle sizes were conducted at $150^{\circ}C$, 75 V condition and the effect of $BaTiO_3$ particle size on the breakdown voltage and degradation characteristics of MLCCs was investigated. The MLCCs were prepared by using the $BaTiO_3$ particles having the size of $0.525{\mu}m$, $0.555{\mu}m$, $0.580{\mu}m$ and Ni-electrode, respectively. The MLCCs which have the particle size of $0.525{\mu}m$, $0.555{\mu}m$, and $0.580{\mu}m$, respectively were confirmed to meet the standard requirements of X5R(change capacitance within ${\pm}15%$ at $-55{\sim}85^{\circ}C$) by TCC(Temperature Coefficient of Capacitance). The effect of the $BaTiO_3$ particle size on the insulation resistance behavior of MLCCs was confirmed by BDV(Breakdown Voltage) measurements and the cause and degree of degradation of MLCCs were characterized by XPS analysis after the accelerated life test. The MLCCs with $0.525{\mu}m-BaTiO_3$ showed better insulation resistance and BDV characteristics compare to other MLCCs and XPS analysis revealed that the MLCCs degradation is caused by the NiO peak and $BaTiO_3$ peak decrease.

김정우,김종철,이상훈,장기택,김정욱,김영재,신터전,현홍근,Kim, Jung-Woo,Kim, Chong-Chul,Lee, Sang-Hoon,Jang, Ki-Taeg,Kim, Jung-Wook,Kim, Young-Jae,Shin, Teo-Jeon,Hyun, Hong-Keun Korean Association for Disability and Health 2011 대한장애인치과학회지 Vol.7 No.2

다운 증후군(Down syndrome, Trisomy 21)은 가장 흔하게 나타나는 증후군으로 대략 1/1000의 확률로 태어난다. 세 개의 유전적 유형이 있지만, 95% 정도가 3개의 21번 염색체를 갖는 비분리 염색체 유형이다. 주된 구강 증상으로는 거대설, 균열설, 과잉치, 결손치, 왜소치, 유치와 영구치의 맹출지연 그리고 이에 따른 부정교합 등이 있다. 75%의 환자에서는 어린 나이에 치주질환에 이환되기 쉬우며, 치아우식증에는 낮은 이환율을 보인다는 보고가 있다. 급성 림프구성 백혈병(Acute Lymphoblastic Leukemia)은 주로 어린이에서 나타나며, 특히 다운 증후군 환자에서의 발병율은 정상인에 비해 20배 높다. 치은비대와 출혈의 양상이 주로 나타나며, 간혹 상악골과 구개골에 종괴가 관찰 되기도 한다. 본 증례에서는 서울대학교치과병원 소아치과에 내원한 환자 중 급성림프구성 백혈병을 앓고 있는 다운 증후군 환아가 있어 이를 보고하고자 한다.

김정우,현홍근,김영재,김정욱,장기택,김종철,한세현,이상훈,Kim, Jung-Woo,Shin, Teo-Jeon,Hyun, Hong-Keun,Kim, Young-Jae,Kim, Jung-Wook,Jang, Ki-Taeg,Kim, Chong-Chul,Lee, Sang-Hoon Korean Academy of Pediatric Dentistry 2012 大韓小兒齒科學會誌 Vol.39 No.1

치아종은 유치나 영구치배의 지속적인 치배 형성이나 법랑기 세포들의 비정상적인 증식의 결과로 발생하는 방사선 불투과성 병소로, 비교적 흔한 치원성 종양이며 인접한 치아의 맹출을 방해 할 수 있다. 치아종은 영구치열기에서 주로 관찰되고, 유치열기에서는 매우 드문 것으로 보고되고 있다. 본 증례 보고에서는 치아종에 의해 매복된 유치가 치아종의 외과적 발거 후 자연 맹출된 증례들을 보고하고자 한다. 매복유치는 계승 영구치의 발육과 맹출 문제를 야기할 수 있기 때문에 치아종이 제거된 후에도 계승 영구치가 맹출할 때까지 장기적인 검사 및 관찰이 필요하다. Odontomas generally appear as small, solitary, or multiple radio-opaque lesions found on routine radiographic examinations. It is a comparatively common odontogenic tumor, and may lead to interfere with the eruption of its associated tooth. In general, odontomas occur more often in permanent dentition and are very rarely associated with primary teeth. This report deals with five rare cases of primary teeth impaction associated with odontomas, with spontaneous eruption occurring in all five cases after simple surgical removal of the odontoma. Impacted primary teeth may be associated with defects in development and eruption of their permanent successors, and thus long-term observation is necessary until the permanent successors erupt.

면역조직화학법을 이용한 점농어 (Lateolabrax sp.) 뇌에서 두 종류 (sGnRH, cGnRH-II) 의 생식소자극호르몬 분비호르몬의 동정

김정우,이원교,양석우,정관식,조용철,노용길,방인철,김광수,임상구,유명식,권혁방,KIM Jung-Woo,LEE Won-Kyo,YANG Seok-Woo,JEONG Kwan-Sik,CHO Yong-Chul,RHO Yong-Gil,BANG In-Chul,KIM Kwang-Soo,KIM Sang-Koo,YOO Myung-Sik,KWON Hyuk-Bang 한국수산과학회 1999 한국수산과학회지 Vol.32 No.3

Two forms of gonadotropin releasing hormone (GnRH) are identified in the brain of adult mature spotted sea bass (Lateolabrax sp.) by immunohistochemical methods. Salmon GnRH immunoreactive (sGnRH-ir) cell bodies were distributed in the olfactory bulb, ventral telencephalon and preoptic region. Immunoreactive fibers were observed in the vicinity of the brain including the olfactory bulbs, the telencephalon, the optic nerve, the optic tectum, the cerebellum, the medulla oblongata and rostral spinal cord. In most cases, these fibers did not form well defined bundles. However, there was a clear continuum of immunoreactive fibers, extending from the olfactory bulbs to the pituitary. cGnRH-II-ir cell bodies were only found in olfactory bulbs. However, the distribution of cGnRH-II-ir fibers was basically similar to that of sGnRH-ir fibers except for the absence of their continuity between the olfactory bulbs and the pituitary. These data suggest that sGnRH and cGnRH-II are endogenous peptides and indicate the presence of multiple neuroendocrine functions in the brain of the spotted sea bass. It seems that sGnRH not only regulates GTH secretion but also functions as a neurotransmitter, whereas cGnRH-II functions only as a neurotransmitter. 성숙 점농어 뇌에서 세 종류의 생식소자극호르몬 분비호르몬 (GnRH)의 소재를 면역조직화학법에 의해 동정하였다. sGnRH 양성 신경세포체는 후각망울, 복측 종뇌와 전시각 지역에 분포하였다. 양성 신경섬유는 후각망울에서부터 척수에 이르기까지 다양하게 분포하였다. 면역신경섬유는 뇌의 전지역인 후각망울, 종뇌, 시각시개, 소뇌, 연수 그리고 머리쪽 척수에서 발견되었다. 대부분의 경우 이들은 모두 다발을 형성하지는 않았다. 그러나 후각망울에서 뇌하수체로 뻗어있는 양성 신경섬유는 가장 뚜렷하였다. cGnRH-II 양성 신경세포체는 후엽에서 발견되었다. 그러나 cGnRH-II 면역신경섬유도 후각망울에서 뇌하수체로 뻗은 면역신경섬유를 제외하고는 기본적으로 sGnRH 양성 신경섬유와 분포가 유사했다. 이것은 점농어 뇌에서 sGnRH와 cGnRH-II가 알려진 내인성 펩타이드이며, 이들이 다양한 신경내분비 기능을 수행할 것이라는 점을 의미한다. sGnRH는 GTH의 분비를 조절 할 뿐만 아니라 신경전달조절자로서, cGnRH-II는 단지 신경전달조절자로서 작용할 것으로 생각된다.

This paper addresses performance analysis of a reciprocating compressor. A computer simulation model has been developed to predict and estimate the compressor performance. Instead of using ideal gas equations, real gas equations are used in describing the state of gas. The compressor simulation model consists of a cylinder control volume, suction system and discharge system. Conservation laws of mass and energy are applied to the cylinder section only, The suction and discharge system are described by the Helmholtz resonator modeling. Some of input data required for the simulation have been obtained from experiments. These experimentally obtained input data are effective flow area, effective force area and dynamic characteristics of valves. Simulation results of real gas equations have been compared with those of ideal gas equations. It has been found that the simulation with real gas equations yields lower cylinder temperature and heat transfer compared with those of ideal gas equations. Differences in pressure, mass flowrates, valve motions and gas pulsations are found quite small.

무연계 Ag 외부전극재의 열충격에 따른 열화특성과 고장해석

김정우,윤동철,이희수,전민석,송준광,Kim, Jung-Woo,Yoon, Dong-Chul,Lee, Hee-Soo,Jeon, Min-Seok,Song, Jun-Kwang 한국전기전자재료학회 2008 전기전자재료학회논문지 Vol.21 No.5

Silver pastes as the outer electrodes have been prepared using Pb-free glass frits with different content of $Bi_2O_3$ and the effects of glass composition on the degradation behaviors of the Ag electrodes were investigated using the change of adhesion between Ag electrode and alumina substrate with thermal cycle stress. Low adhesion and high surface resistance were observed in Ag electrode using glass frit with a $Bi_2O_3$ content of 60 wt%, owing to the open microstructure formed at the firing temperature of $600^{\circ}C$. When the $Bi_2O_3$ was increased to 80 wt% in the glass frit, the Ag electrodes had a dense microstructure with high adhesion and a low surface resistance. Delamination of the Ag electrodes was a major failure mode under thermal cycle stress and this was attributed to residual stress due to the thermal expansion mismatch between the Ag electrode and the alumina substrate.

Immune Modulatory Effects of Mesenchymal Stem Cells Mediated by Lymphocyte Recruitment

김정우,Cha Je-Eun,Choi Da-Won,Kim Hyeonju,Cho Kyung-Ah,Woo So-Youn 대한미생물학회 2024 Journal of Bacteriology and Virology Vol.54 No.2

Immunomodulators, including recombinant proteins, immunoglobulins, and cell therapeutics, can activate or suppress the human immune system. Mesenchymal stem cells have immunoregulatory functions and could be used as cell therapeutics. In this study, we hypothesized that exogenous MSCs would regulate the immune response by influencing the recruitment of T lymphocytes in peripheral tissues. In a mouse allogeneic bone marrow transplantation model, bone marrow with MSCs from C57BL/6 mice (H-2b) was transferred to BALB/c mice (H-2d) pre-conditioned with busulfan-cyclophosphamide. The proportion of CD3+ cells in the spleen was lower in the MSC co-transplantation group. When MSCs were administered, the expression of CD69 decreased in the spleen, while CD62L increased in the blood. In vitro, T-MSC co-cultured splenic T cells showed decreased expression of CCRL2, ACKR2, IFNG, TLR4, CXCR2, CCL5, CCR5, IL4, and CCL20 and increased expression of CXCL9, ACTB, CXCR6, CCR9, CCR4, CCL28, and MAPK1. This study provides a clue to the immune modulatory effect of MSCs by regulating lymphocyte migration in the peripheral lymphoid tissues by secreting chemokines, inducing chemokine receptor expression, or CD69-mediated regulation.

김정우,김춘수,박근식 ( J . W . Kim,Chun . S . Kim,K . S . Park ) 한국축산학회 1990 한국축산학회지 Vol.32 No.11

The reduction properties of backfat thickness PI, P2, P3 and Pm in Suilin treated group were 14.3%, 15.5% 15.6% and 15.1% in compared with those of control group, respectively. These results are found to be more noticeable than that of Wood et al. $lt;10.9% : P2) and somewhat comparable to that of Kilpatrick (18.8%: P2). The increased rate of backfat thickness P1, P2, P3 and Pm in Suilin treated group during whole period of this experiment were -28.9%, -23.4%, -30.4.%and -27.6% in compared with those of control gorup, respectively. The effect on growth rate does not seem to be significantly influenced by treatment. However, some effects of treatment on carcass quality were found. Suilin treated pigs have higher lean% and ham% than untreated pigs. In addition, there seem to be a tendency that the treated pigs have better results on killing-out proportion, fat% and chilling loss%, even though there are little statistically significant differences. As a conclusion, the general effects of Suilin are to reduce backfat thickness while having some additive effects on carcass quality and little effect on growth rate.
